Application filed July 10, 1916. Serial No. 108,419.

To all whom it may concern:

Be it known that 1, MICHAEL P. McNUInY, a citizen of the United States, residing at Whitney, in the county of Stanly and State of North Carolina, have invented new and useful Improvements in Railway Construction, of which the following is a specification.

The present invention relates to improvements in railway construction.

An object of the, invention is to produce a tie comprising a trough-shaped metal member having spaced sides and a central compartment, reinforced plastic material filling the spaces between the sides and filling the central compartment, and removable means being arranged in the channeled ends of the ties and secured thereto for supporting and for retaining the rails upon the ties.

With the above and other objects in view the improvement, resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claims.-

, from the oppositesides ofits web.

In the drawings, 15 designates the rails and 16 the ties which support the rails.

The rails 15 are of the ordinary construction having the usual bolt openings passing through the webs thereof, 'but if desired the rail, as illustrated in Fig. 11, may have its ends integrally formed with a plurality of laterally extending studs 17 or as illustrated in Fig. 12, the rail end may be provided on each side with a single substantially rectangular lug or stud 18 projecting Each of the ties 18 includes an inner metallic channel member which from its ends, to a suitable distance from its center, is rectangular in cross section, and the parallel sides of the said ends have their edges bent or-otherwise provided with longitudinally extending grooves 20. The central portion of the channeledmembers comprises a substantially ll-shaped trough and is divided from the rectangular end portions by vertically disposed partitions 21--21 which project above the edges'of the said channeled member, as shown in the drawings. The tie also includes an outer substantially U-shaped metallic member 22 that is adapted to inclose the inner metallic member 19 thereof, so that the sides 23 of the said member 22 are spaced from the sides 24 of the inner member 19 and the member 22 has its central portion formed with an inturned substantially V-shaped trough 22 which is adapted to receive the referred to trough of the inner member 19. The base 26 of the member 19 rests on the horizontally straight base 25 of the outer member 22, and if desired both the inner and outer members may be constructed of sections which are suitably connected, at the base portions thereof, and the base 26 of the member-19 is connected with the base 25 of the member 22, preferably by rivets, as disclosed in the drawings. It is to be understood that when the member 22 is constructed from a single element it has its base also connected with the base of the inner member 19. If desired the partitions 21 may extend over the top edges of the sides of the inner member 19 and be arranged in a line with the outer edges of the the outer member 22 are provided with longitudinally extending openings 28, and the bottom 25, at the space between the sides 23 of the outer member and the sides 24 of the inner member are likewise Provided with elongated openings 29. Both of the openings 28 and 29 extend almost the length of the tie and the said openings are provided to permit of the plastic filler 30 which is inserted in the space between the sides of the inner and outer member, to pass through the said openings and thus obtain a firmer hold upon the metallic shell of the tie., The box formed at the central portion of the tie and provided by the partitions 21-21 and the longitudinal members 27 connecting the said partitions is also adapted to have tamped therein a filler of plastic material, indicated by the numeral 31, and this filler may have,. and preferably has, arranged therein metal reinforcing rods.. The side filler 30 is reinforced by the vertically disposed arms 32 of substantially U-shaped metal rods 33, the connecting member for the rods being disposed transversely of the bottom or base 25 of the tie.

Passing longitudinally through the box at the center of the tie and if desired secured to the partitions 21 as well as being provided with means for. engaging with the plastic filler 31 in the said box, is a rod or bolt member 34. This bolt member is disposed centrally of the tie, and is preferably arranged above the grooves 20 in the inner member 19 of the tie and has itsends ter minating with or slightly inward of the ends of the tie. The ends of the bolt 34 are threaded, as at 35.

The open ends of the tie are adapted to receive each a substantially rectangular block 36, and the rail engaging members 37 rest upon these blocks and are secured thereto in a manner which will presently be described. The blocks may be in the nature of wooden blocks and each of the same, at a suitable distance from its center, and upon its, upper face is formed with depressions 38, while each of the blocks is provided with a longitudinally extending opening 39 that communicates with the depressions, and the ,bolt members 34 are adapted to pass through the openings 39.

The rail engaging members are arranged in pairs, two of the co-a-cting members being positioned upon each of the blocks 36, and each of the said rail engaging members includes a horizontally straight flange 40 upon which the base flanges of the rails are received and vertically disposed plates 41 which have their inner facesshaped'to correspond with and which are adapted to be received in the fishing spaces on the sides of the rails. The plate of one of the rail engaging members may be provided with studs 42 which are adapted to be received in the bolt openings of the webs of the rails, or as shown in the drawings, the said plates may be provided with openings to receive the studs 17 in the rail ends, while still again the plates may be provided with elongated openings 44 to receive each one of the lugs 18 upon the rails. The members 40 and 41 are of a width preferably greater than the cross. sectional width of the tie and integrally formed with the flanges 40 and connected to the vertical plates 41 by integral members 45 are outwardly extending hoods 46. The hoods 46 include spaced sides which have their lower edges formed with tongues or flanges 47, which are adapted to ride in the grooves 20 of the central channeled member 19 of the tie. The outer straight angular ends of the hoods, indicated by the numerals 48, depend a suitable distance below the tongues or flanges 47 and these end plates are adapted to contact with the ends of the blocks 36. The end plates are also provided with openings 49 i openings for the reception of securing ele ments 50 which enter the blocks 36. The upper plate of each of the hoods forward of its outer plate 48 is formed with a downwardly extending ear 5,1, which is adapted to be received in one of the depressions 38 in the blocks 36, and is provided with an opening which receives the rod 34.

The threaded ends of the rod 35 are en gaged by nuts 51"which may also contact with washers 52 disposed upon the rod 35 between the end plates of the hoods and the said nuts, and by this arrangement it will be noted that the rail securing elements may be effectively sustained at a desired position with relation to the tie, and also that the blocks, together with the said rail securing'elements, may be easily and quickly removed from the tie. If it is desired that only the outer rail engagingelement be removed this can be readily accomplished without interfering with the inner rail en gaging element or member as will, it is thought, be readily understood. The longitudinally extending rod may be threaded throughout and, if desired, adjusting elements, in the nature of nuts 52 may be positioned upon the rod between the blocks and the partitions so that when the said bolts are screwed in the direction of the blocks and the outer nuts 51' are loosened upon the rod the blocks and the rail engaging members carried thereby maybe sustained out of contact with the partitions, and thus it will be noted that the blocks and therail engaging elements may, if desired, be sustained at any desired position upon the tie.

It is to be noted that the substantially central \I-shaped portion of the tie will permit of the tamping of the roadbed therein, so as to effectively retain the tie against longitudinal movement, while the flat base of the tie to the opposite sides of the said central V- shaped portion will prevent thwsinking or lateral movement of the said tie, and the additional advantages of the structure will, it is thought, be apparent to those skilled in the art to which such invention appertains.

Having thus described the invention, what I claim is:
